Rimowa Salsa vs Salsa Air

[KenRose]

Hi all. I know there are a few Rimowa users here; I'm looking to buy a 29 or 30 inch suitcase to replace my old one. Normally I just travel carry on but each year spend a month in NYC. Next year I'm also thinking about going to Europe. So I have decided on Rimowa after some research but am now stuck on the Salsa vs the Salsa air. I do like the weight savings of the salsa air and don't care about that single rod handle as I won't be stacking luggage. My concerns are on the inside as I'm assuming clothes will shift around within those mesh pockets. Would appreciate some views from users here.
Also not sure if I should go with the 29 or the 30 inch. I'm a 44 suit so I'm going to bring one in a garment bag to the store to see if the 29 will be too narrow.
Would appreciate some thoughts.
